[PATCH v7 0/5] mfd: tps6586x: register restart handler

by Benjamin Bara

Hi! The Tegra20 requires an enabled VDE power domain during startup. As the VDE is currently not used, it is disabled during runtime. Since 8f0c714ad9be, there is a workaround for the "normal restart path" which enables the VDE before doing PMC's warm reboot. This workaround is not executed in the "emergency restart path", leading to a hang-up during start. This series implements and registers a new pmic-based restart handler for boards with tps6586x. This cold reboot ensures that the VDE power domain is enabled during startup on tegra20-based boards. Since bae1d3a05a8b, i2c transfers are non-atomic while preemption is disabled (which is e.g. done during panic()). This could lead to warnings ("Voluntary context switch within RCU") in i2c-based restart handlers during emergency restart. The state of preemption should be detected by i2c_in_atomic_xfer_mode() to use atomic i2c xfer when required. Beside the new system_state check, the check is the same as the one pre v5.2. --- v7: - 5/5: drop mode check (suggested by Dmitry) - Link to v6: https://lore.kernel.org/r/20230327-tegra-pmic-reboot-v6-0-af44a4cd82e9@skid… v6: - drop 4/6 to abort restart on unexpected failure (suggested by Dmitry) - 4,5: fix comments in handlers (suggested by Lee) - 4,5: same delay for both handlers (suggested by Lee) v5: - introduce new 3 & 4, therefore 3 -> 5, 4 -> 6 - 3: provide dev to sys_off handler, if it is known - 4: return NOTIFY_DONE from sys_off_notify, to avoid skipping - 5: drop Reviewed-by from Dmitry, add poweroff timeout - 5,6: return notifier value instead of direct errno from handler - 5,6: use new dev field instead of passing dev as cb_data - 5,6: increase timeout values based on error observations - 6: skip unsupported reboot modes in restart handler --- Benjamin Bara (5): kernel/reboot: emergency_restart: set correct system_state i2c: core: run atomic i2c xfer when !preemptible kernel/reboot: add device to sys_off_handler mfd: tps6586x: use devm-based power off handler mfd: tps6586x: register restart handler drivers/i2c/i2c-core.h | 2 +- drivers/mfd/tps6586x.c | 50 ++++++++++++++++++++++++++++++++++++++++++-------- include/linux/reboot.h | 3 +++ kernel/reboot.c | 4 ++++ 4 files changed, 50 insertions(+), 9 deletions(-) --- base-commit: 197b6b60ae7bc51dd0814953c562833143b292aa change-id: 20230327-tegra-pmic-reboot-4175ff814a4b Best regards, -- Benjamin Bara <benjamin.bara(a)skidata.com>

[PATCH] SELinux: Check correct permissions for FS_IOC32_*

by Alfred Piccioni

Some ioctl commands do not require ioctl permission, but are routed to other permissions such as FILE_GETATTR or FILE_SETATTR. This routing is done by comparing the ioctl cmd to a set of 64-bit flags (FS_IOC_*). However, if a 32-bit process is running on a 64-bit kernel, it emmits 32-bit flags (FS_IOC32_*) for certain ioctl operations. These flags are being checked erroneoulsy, which leads to these ioctl operations being routed to the ioctl permission, rather than the correct file permissions. Two possible solutions exist: - Trim parameter "cmd" to a u16 so that only the last two bytes are checked in the case statement. - Explicitily add the FS_IOC32_* codes to the case statement. Solution 2 was chosen because it is a minimal explicit change. Solution 1 is a more elegant change, but is less explicit, as the switch statement appears to only check the FS_IOC_* codes upon first reading.
